Upload loading state

When uploading the file you can set the loading state of the request using the Upload.useUpload hook and passing isLoading to the file that is being uploaded.

render(<Component />)

Upload error message

The only file verification the Upload component does is for the file size and the file type. These errors are handled by the HTML element input so they aren't selectable. If you want any other error messages you can use the Upload.useUpload hook the same way as with the loading state.

Upload specific accepted file formats

Upload without file max size

You can disable the file max size, which will deactivate all file size verifications in the Upload component. This can also be used to manually implement more complex file max size verifications.
